Revamped Distribution Scheme – Another Effort to Reform the Indian Electricity Distribution Sector

In earlier blog, we discussed in detail a major problem plaguing the electricity sector in India – ensuring financial viability of Distribution Utilities (DISCOMs). We noted how this objective has long been a policy focus for successive governments and discussed a new Central Government scheme aimed at ensuring financial viability of DISCOMs; a scheme which …

Leakage Current and Monitoring of GIS Lightning Arresters

In an earlier blog, we discussed the techniques and methodologies for health assessment of lightning/surge arresters.  We also shared our knowledge on the various methods of measuring resistive leakage current or power loss. In the following blog, we answered the 10 most frequently asked questions on the various aspects of testing and measuring lightning/surge arresters. …

How to do Condition Assessment Diagnostics of Generators?

Over the years, power generation in India has grown manifold: installed capacity has increased from 1.36 GW in 1947 to 382.73 GW as on April 2021 (Source: CEA). Therefore, maintenance of generators is critical to ensuring uninterrupted quality power to the country. Apart from the generator, the HT transformer and the HT motors play a …

Success Story: Accurate Prediction Of Voltage Violation Alerts – On Time, Every Time.

Most of the Low-Carbon Technologies (LCTs) used today (mainly EV battery charging, rooftop solar systems and data centre loads) are all non-linear loads. Ohm’s law is not applicable to such loads, meaning that the current is not proportional to the voltage and fluctuates based on the alternating load impedance. Utilities face many problems as their …

DCRM Testing For High Voltage Circuit Breakers: What, Why, How

High Voltage Circuit Breakers (HV/EHV/UHV) act as the most effective protection mechanism against electrical mishaps in the high voltage environment of Substations. Since Circuit Breakers (CBs) are mechanical devices, they are vulnerable to breakdowns if timely performance tests are not conducted to ensure their functional healthiness. In our earlier post, we broadly covered the 9 …

9 Fundamental Tests For High Voltage Circuit Breakers

When it comes to the cohesive protection of man, machine and infrastructure from electrical mishaps, Circuit Breakers (CBs) play a linchpin role, especially in the high-voltage (HV) environment of Substations. With rapid advancements in technology, while the quality of HV CBs has definitely improved over the last few years leading to a significant drop in …
